A. Entisol and problem
Posted On 11/05/2011 04:17:23 by Chahaat

Entisol ('ent' comes from the recent word) is a mineral soil that is not
have horizons that characterize pedogenik (Soil Survey Staff, 1998).
Entisol characterized by a mineral soil horizon that has not been established
real diagnostic for weathering a new beginning or the parent material is difficult
soluble as quartz sand, or form a hard rock like the slow dissolution
limestone, or topography is sloping so that erosion rate exceeds
pedogenik horizon formation (Darmawijaya, 1990).Soil Survey Staff (1998)
Entisol differentiate into 5 suborders, namely Aquents, Arents, Fluvents, Orthents
and Psamments.
Suborder Aquents akuik represent conditions and sulfidic materials within 50 cm
from the mineral soil surface; or always saturated water and the matrix is ​​reduced to
all horizons below a depth of 25 cm of mineral soil surface, etc.. Entisol
others who have one or more layers between depths of 25 and 100 cm in
subsurface mineral soil, have fragments penciri horizon of 3 percent
or more that are not composed expressly include Arents suborder. Psamments
is Entisol that has rock fragments and fine sand texture berliat
or more roughly by less than 35 per cent, on all layers in the
cross section of a large class of control egg. Entisol that have non-contact
densik, lytic, or paralytic within 25 cm of mineral soil surface and
has a slope of less than 25 percent, 0.2 percent organic carbon or more on
depth of 125 cm below the mineral soil surface and the hotter the temperature regime
of cryik included in the suborder Fluvents, and Ortents is Entisol the
Other (Soil Survey Staff, 1998).
The physical properties Entisol mostly not good. Generally, the main obstacle
This soil is accompanied by a lack of physical properties of water (Komar, 1984). Entisol have
clay and organic matter content is low, so low water holding power,
crumb structure until grained and very nest, this causes the soil
is easy to pass water and water easily lost due to percolation. Because
The organic matter content is low, efforts to improve the physical properties and
soil chemistry is the addition of organic material, so that the physical properties and
soil chemistry can be corrected with the function of the organic material.
